[sr-dev] ims_diameter_server and cdp modules modification

Hello, I used from kamailio with MMTel features as AS in my IMS scenario and I wanted to send UDR diameter request from AS to my HSS. According to my study I should use "diameter_request" or "diameter_request_async" in ims_diameter_server module . but some problem exists in diameter_request function which caused "json" string as input of "diameter_request" ignored and fault happened. I added parse and checking "json" string in diameter_request function in ims_diameter_server.c file : if (message) { if (get_str_fparam(&s_message, msg, (fparam_t*)message) < 0) { LM_ERR("failed to get json string\n"); return -1; } LM_DBG("json %.*s\n", s_message.len, s_message.s); } also cdp_get_session function in cdp module has problem with "lock and unlock session" and " AAASessionsLock(hash); " doesn't work correctly. I comment " AAASessionsLock(hash);" and " AAASessionsUnlock(hash);" I recompiled ims_diameter_server and cdp modules again called below part in request_route of my configuration : if(is_method("REGISTER")) { diameter_request("hss domain address", "16777217", "306", "{ 'avpCode':263 , ....}"); } this worked correctly and UDR request sent to hss .
